SPECTRUM ANALYZERS

A spectrum analyzer of the type where input signals to be analyzed are mixed with a repeatedly swept frequency signal so that output signals are provided which are time related to the frequency of the input signals. The repeatedly swept frequency signal is produced by applying a train of pulses to a...

Beschreibung
Zusammenfassung:	A spectrum analyzer of the type where input signals to be analyzed are mixed with a repeatedly swept frequency signal so that output signals are provided which are time related to the frequency of the input signals. The repeatedly swept frequency signal is produced by applying a train of pulses to a dispersive delay via a bandpass filter having a characteristic such that the impulse spectrum of each of the pulses in the pulse train is reduced so as to match that of the dispersive delay.
